* devres: fix possible use after freeMaxin B John2011-07-251-1/+1
| | | | | | | | | | | | devres uses the pointer value as key after it's freed, which is safe but triggers spurious use-after-free warnings on some static analysis tools. Rearrange code to avoid such warnings. Signed-off-by: Maxin B.

* genirq: add support for threaded interrupts to devresArjan van de Ven2009-03-241-6/+10
| | | | | | | | | | | Some devices use devres_request_irq() for to install their interrupt handler. Add support for threaded interrupts to devres as well.

* kernel: explicitly include required header files under kernel/Robert P. J. Day2008-04-291-0/+1
| | | | | | | | | | | | | | Following an experimental deletion of the unnecessary directive #include <linux/slab.h> from the header file <linux/percpu.h>, these files under kernel/ were exposed as needing to include one of <linux/slab.h> or <linux/gfp.h>, so explicit includes were added where necessary.

* [PATCH] irq-devres: fix failure path of devm_request_irq()Tejun Heo2007-04-071-1/+1
| | | | | | | | | | devres should be deallocated with devres_free() not kfree(). This bug corrupts slab on IRQ request failure. Fix it.

* [PATCH] sort the devres mess outAl Viro2007-02-111-0/+88
* Split the implementation-agnostic stuff in separate files. * Make sure that targets using non-default request_irq() pull kernel/irq/devres.o * Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive; allow architectures to turn them off (we needed these symbols anyway for dependencies of quite a few drivers). * protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.
